SUCTION GAS PLANT.

Application lerl September 9, 1922. Serial No. 587,209.

To all 'whom it may concern,.-

Be it known that I, GUsfrAv ERDBRGGER, a citizen of the German Republic, residing at Bad Oeynhausen, Germany, have invented certain new and useful Improvements in Suction Gas Plants, of which the following is a specication.

In suction gas plants for the productlon of power gas the gasification of bituminous fuel can be carried through only if the plants are tted with a generator.

In vgenerators using anthracite coal or coke a mixture of air and steam is injected into 4 the generator below the grate to lbe decomposed by the coke heated to incandescence and drawn off as power gas by the suction of the engine. j

In the gasification of bituminous fuel the process is reversed. The jet of gasifying air is injected above the layer of coal and the power gas is drawn oil either directlyA below or above the grate or directly from the incandescent layer.

By this method the inconvenient tar vapors and the gases from distillation are transformed into combustible gases suitable for the working of the internal combustion engine.

This invention relates to a suction gas plant for yinternalI combustion engines as well as for reheating and tempering furnaces in which plant without any change of construction, but merely on adjustment of a valve, either bituminous or nonbituminous fuels can be gasified. Y

This result is obtained by injecting the jet of steam and air into the gas generator Ibelow the grate ifanthracite, coke, or charcoal is used and the gas is drawn off at the top whilst if brown coal, briquettes, peat, wood, or the like are used the air jet is injected above the layer of fuel and the gas is drawn o' immediately below or above the grate or even directly from the fuel.

The improved suction plant according to the invention could further bevused as a generator for motor driven cars, the generator being of small dimension and little weight` and adapted to be operated from the motormans seat. 5

In order to make'my invention clear, the saine is more or less diagrammatically illustrated in the accompanying drawings showing one embodiment of my invention and 1n which:

Fig. l is a vertical section of the improved gas generator for the gasification of anthracite, coke, or charcoal and it is a section on line A B of Fig. 3.

Fig. 2 shows the same gas generator for the gasification of brown coal, briquettes, peat, wood or the like and is a section on line C--D of Fig. 4.

Fig. 3 is a plan view of the improved gas l up of refractory bricks, as usual. The same is provided at its bottom with a grate `b and is arranged eccentrically in a casing C.

`(Figs. 3 and 4). The space in the casing around and below the chamber c is parti tioned ofi as best shown in F igs. 4 and 6t to form two adjacent chambers z', Lof substantially crescent shaped cross section, of which one, say i, serves as a' gas purifying chamber and the other L, as a gas drying chamber. Between these chambers and the gas generating chamber are formed intermediate chambers o, p, which are open on top,V to the atmosphere and which are adapted to communicate with one another through lateral passages (not shown). Below the chambers a', L a gas collecting cha-mber 'n is formed. At thesides of the gas generating chamber flues e, it and c are provided of which'flues kL, and o are -ar-.

ranged adjacent to one another at one side of the chamber and line e at the opposite side of the latter. On the open top of the gas generating chamber c around the charge opening or dome c of the latter is mounted an annular cup ,f which is adapted: to serve as a steam generator and to have al water pipe connection (not shown). Leading kfrom n this cup is a tube g2- from which are branched off two tubes Lg and g', the

tube g terminating in the flue e and the tube generator c and the puriier Y the like.

g extending through the dome and termi- Vfrom the top of the chamber c are two tubes,

a tube rl controlled by a valve Z andY leading into the atmosphere and a tube s leading through branches it', o into the tlues h and fvrespectively and connected to said branches by a two way cock or valve fw. The liue 7L` at its bottom is extended below the ash pit and communicates through passages h2 and h3 with the purifying chamber a.'

The flue c communicates at its bottom with the ash pit t through a passage a (Fig. Leading from the top of the purifying chamber 7l into the adjacent chamber L is a pipe la which terminates near the bottom of said chamber L. Leading from a point near the top of and extending vertically through said drying chamber L is a pipe which projects into the gas collecting chamber a (Fig. 62). rlhe latter has a discharge passage a from which the generated gases may in a suitable manner be conveyed to a motor or a denotes a suitable hand pump connected to the flue e and by means of which starting air can be blown under the grate b of the chamber c for the starting of the generator. The air blown in by the pump t is transformed into the chamber cinto power gas and other gases which are allowed to escape into the atmosphere through the valve CZ. i

One object of arranging the intermediate chambers 0 and 7a between the heatedl gas chambers e' and L is to permit the air entering the gas generator to be preheated before passing into the cup f.' Another object thereof is to insulate the chambers a', L, from the walls c2 of the gas generating chamber 0, so as to prevent the gases flowing therethrough from being heated.

The operation of the generator is vas fol-y lows: s

' When anthracite fuel is used, steam has to i be produced by feeding` water in a suitable manner into the cup fto produc-e the preliminary heating of the gasified air. Starting air is blown under the grate h by means of the hand pump ai and the gases formed permitted to escape through the `reversing valve al. `When the engine is to be started the valve d and the air pump am are closed and the air to be gasitied enters the evaporation cup f from the chamber 0 through pipe g.

The cock r having previously been correspondingly adjusted, permits the air to pass from thel cup f into the flue e through which it enters the ash pit t and thence, (the valve w having been closed to the tine '0), rises through the grate Z) into the generating chamber c. The power gas produced in the latter passes out through the tube s, valve w into the flue h and throughthe latter into the purifier chamber i. From the latter it passes through the pipe 7c into the drying chamber L and thence through the pipe 'mr into the gas collector n from which it may be supplied to the engine.

For the gasification of bituminous fuel, the water contained in the fuel is sutticient to produce the desired quantity of steam and therefore no additional water need be dropped into the evaporation Icup f. ln this case, the cock r having been closed to the iue e, the air passes from above into the generating chamber c from the evaporation cup f through the pipe g, and as the cock w closes the pipe s, the gas produced in the chamber c will now pass downwardly through the grate b into the ash pit t, thence through the port u into the flue o and thence through the valve fw, fine it into the purifier 7l and from the latter as in the first case through the pipe 7c into the drying chamber L then finally through pipe m into the collecting chamber a.

The two cocks r and fw may be connected to one another by a rod x, so that by turning a handley an angle of 900 the cocks r and w will be adjusted for the generation of gas from one to another kind of fuel to be used. Y

In testimony whereof I affix my signature in presence of two Witnesses.
